Rslinx OPC server OPCinterface

I have a RSlinx OPC server running on my local PC and was looking to create a link between it and the OPC interface in Plant sim. It is functioning on an excel spreadsheet. If there is anyway to do so I appreciate the help. Or even a basic guide to linking it with RSlinx or an alternative program to Plant Sim.

Mostly just wondering what the server name would be and if it will connect by just filling it in
